Hey@davidcraven02,
You need to check the following points:
1. Was the app being pushed on the hosts from which data is not coming?ie, the app having inputs.conf.
2. Check if any error are coming in index=_internal for that particular host if not sending data.
3. Check if the followtail logs are coming in _internal for those particular host.
4. If all these conditions are satisfied then your problem has to be crc_salt , Removing crc_salt should solve this but might also re-index the data which is already indexed.
5. Also you can check initCrcLength for the issue.
